摘要：

A blue‐emitting phosphor CaGdGaO4:0.005Bi3+ with high IQE of 93.7% and EQE of 70.5% is synthesized. The high thermal stability of 80.1% (@ 150 °C) is achieved. The blue and red dual‐emitting are achieved by co‐doping activators. The blue‐emitting can efficiently enhance the photosynthesis and seeding index of rice. These phosphors are promising for full‐spectrum WLED and plant fill light. Abstract Since Bi3+‐activated phosphor are widely reported in phosphors‐converted light‐emitting diodes (pc‐LEDs), developing new‐high efficiency p...
